Galesburg, ND: when does the frost end?
The last spring frost here typically falls around 05/13, about 258 days from today. Fall's first freeze usually shows up around 09/27, roughly 136 days after the last spring frost.

Stretching the season past the first frost
With roughly 4 weeks until Galesburg's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/13 isn't a guarantee
05/13 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/25 and only about 1 year in 10 sees frost after that.
